To all whom it may concern:

Be it known-that I, DANIEL E. REAGAN, a citizen of the United States,and a resident of Columbus, in the county of Franklin and State.of'.Ohio, have invented certain new and useful Improvements in'Brickmaking- Machines; and I do hereby declare the fol- "lovfvingt'o bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains tomake and usethe same.

My-invention relates to an improvement I in'brick making machines.

Heretofore in the manufacture of paving bricks or blocks havingprojections on one or more facesfor holding them apart so as to permitthe cement, grout or other filler commonly used for bonding purposes, tobe readily poured-or inserted between the bricks or blocks, and whichalso, facilitate the laying of saidbricks by'=keeping them alinement,these projcction's'. .have been formed by repressing the bricks, andalso by rollers or other pressure devices anpliedtet-hc lav molded bythe die. These devices are obfjectionable because of thecost ofrepressing,

quent application of pressure to the clay; bardeforms the clay'bar, andunless the pressure be considerable, the clay will not be forced up fromthe unconfined clay bar into the recesses in the roller or otherpressure device, 'so as to form the projections, regular in size and.shape.

The objcctiof my invention is to provide a roller which forms one-sideof a face of the die, so that the clay as it is forced through the diewill be forced positively into any recesses in the latter.

A further object is to provide means for rotating the roller section ofthe die at the same speed of travel ofthe clay bar through the die, sothat there will not be any dragging or shearing strains on the said lugsor projections.

With these and other objects in View my invention consists in the partsand combinations of parts as will be more fully delongitudinal sectionthrough one of the diesi 'F 1g. 3 1s a View in front elevation of thedie plate carrying the roll and driving gear I forsame; Fig. 4 is a planview and Fig. 5 a view in end elevation of the same.

In the drawings ,1 have shown a double stream die for making two claybars at a time, but I would'ha've it understood that my improvement isequally applicable to a smgle d1e machine.

1 represents the head of a brick making through-which the clay isforced, and 2v is a gate secured to the outer open end of the head 1 bythe hinges 3 at one side and by machine, to which the die is attachedand size, shape arid construction except'that the ,top is open toreceive the roll 5, which latter I forms the ton of the. die. whiletbesides and tom and side walls 6 and 7 respectively,

formed integral with each other and also with the die plate.- The sidesor side walls 7 of the die are connected at'their outer ends by theintegral cross member 8, and the side members are provided attheir topwith the:

semicircular bearings 9 in which theshaft v 10 having the IOllS'fithereon, are mounted and in which it is secured by the removable halfbearings 11, secured by screws to the upper edge of the sidewalls of thedie. The rolls 5 may be integral with the shaft or made separatetherefrom and secured thereto by keys or otherwise. The roll or rollsare so located with respect to the head 1 of the machine, that the shapeof the clay bar or column, is not fixed or complete until it engages theroll, so that the pressure against the clay which forces the latter outthrough the die, will force it up and into contact with the roll, thuscausing the clay to enter and fill the recesses 12 in the rolls andproduce corresponding projections, on I i the upper face of the clay baror column, while the smooth portion of the surface of the roll acts as awall for the die. The top i wall of the die, or the lower face of crossbar 8 'is elevated sufiiciently so as not to engage theprojections onthe clay bar orcolumn.

The rolls, or roll shaft 10, is provided at may be used for shaping twofaces, but I i one end with the pinion 13, which meshes prefer one. Thelugs orprojections 25 are with the large gear 14, secured on shaft 15preferably curved as shown and are so lo-' Which' is mounted at one endin bearing 16 cated that each brick or block formed will 5' formed in aside wall 7 of the die, and at the have a plurality of projections onone side,
